Today developer Aldostools has released a new unofficial version of Fan Control Utility. Check out the changelog and the download link provided below.

Developer Notes:
This is an unofficial version of Fan Control Utility by Estwald that auto-quits immediately to XMB after set the fan policy. Hold (X) for 10 seconds to enable the GUI. The settings will be saved in the internal HDD, if the included PKG is installed and dev_hdd0/game/CTRLFAN00/fan_speed.dat exists.

Note:
The AUTOBOOT.ISO for COBRA 7 auto-quits. There are 2 PKG files: one has no GUI, the other always shows the GUI. If you use CFW COBRA 7, you can use the Dynamic Fan Control option in webMAN 1.30 or webMAN-MOD 1.30.x
